ing ixtures and more particularly to a bypass valve and covering therefor used 1n connection lwith bathtub fixtures which embody in connection with the bathtub a shower attachment, the valvesl controlling such shower"v being arranged in the wall at the rear ofthe tiling.

A ride for covering not only It frequently happens thatI it is necessary to replace washers for vvalvefacings and in order to do so,it is necessary to cut olf the water supply fromthe valve casing. This could be accomplished by having a separate valve in the line but according to my invention I propose' to arrange a supplemental cutoff valve in the valve casing proper an in close proximity to the main valve, which. lsupplemental valve can be closed Whenever* it' is desired to make any repairs to the v'valve proper. vj .n

Anotlierobject 0f` my invention is te prothe valve proper but also the supplemental valve.

I. shown in elevation.

lVith these various -objects in viewLmy invention consists in-the novel features of construction and combination all of vwhich .will he fully describedhereinafter and` set` forth in the appended claims.

In the drawing forming a part of this specificationl the figure is a vertlcal sectional view of a by-pass valve connected in accordance with my invention, certain parts being Referring to the drawing, A indicates the water suply pipe in which is interposedthe valve casing B having the partition C .provided -with an opening D which'may be closed by the supplemental cut-off valve E. The partition C is also provided with a threaded opening F into which is screwed the tubularl valve seat G extending a considerable distance into the cylindrical chambered portion H of the valve casin this cylindrical portion H being of such ength;

as to extend'substantially throughthe wall l and tile facing I.

Seated upon the tubular valve scat G is the valve I( having a detachable facing L, the valve K being carried at the innernd of the stem `M which is enlarged and threaded at M, this, threaded portion engaging the internally threaded portion H of the chambered portion I-I.v T he stemt M `extendsoutwardly a suiicient distance and `has the operating handle or knob N detachably connected thereto.

The outer end of the chambered ortion of .the casing H is closed by means o a gasket O and thisin turn has another gasket O inserted in the outer end thereof and confining the packing O2.

In practice, I prefer to have an externally threaded tube P screwed into the gasket O cnmmnAlvn,y omo, AssIeNon. To THE REPUBLIC muss cour-ANY, or.

ardthrough which the stem M pro]ects, this threaded sleeve serving as a guide for the stemtand yalso as a-means 'forsecuring the escutcheon Q, preferably of porcelain Awhich surrounds the stem and conceals the'valve casing and also the opening inthe wall and d tiling, this escutcheon being fastened and positioned bv means of a capR surrounding the stem fitting into the outer end ot the vescutcheon and having threaded engagement with the externally threaded tube P.

The supplemental cut-'cit valve E has a stein E* externally threaded at E2, said stem being located in a housing S screwed into the easing and extending parallel with the cylindrical portion I-I of the valve `casing proper, this housing S extendinginto the'- epeningin the wall and having its outer end closed by means of a gasket'T through which the outer end of the stem E works, the extreme outer end being slotted as Shown at E3 -for the reception of'a screw driver for the purpose of turning the/stem E to operi ate the supplemental cut-olf valve E. The

.outer end of the housing S is also enclosed `within and concealed bythe escutcheon Q,

as most clearly shown in the drawing.

In the Ordinar use of the device the su plementalvalve is opened as indicated 1n the drawing.

If for any ,reason it'should vbeldesired to replace orrepair the valve 'or'any of the akings thereof, the handle or knob N can be detached from the valve stem, the escutcheon removed, and by turning the valve stem E in the proper direction the supplemental cut-olf Valve E can be seated in the opening D, cutting oft' the supply of Water to the valve casing proper. The valve K can then be removed for the purpose of making `any repairs, replaced and then the supplemental cut-olf valve E can be opened again and lthe escutcheon and operating handle or knob replaced.

It will thus be seen that I provide in connection With the Wall valve casing a supplemental cut-off valve Which can be quickly and easily operated When necessary, and that I also provide meansfor concealing not only the operative parts of the valveproper but also the supplemental cut-off valve.

Having thus described my invention, what I claim is 1. The combination with a valve casing having a main valve and stem, said stem extending through a wall opening, of a supplemental cut oli' valve and stem, said stem extending into the Wa/ll/ opening, and an escutcheon arranged upon themain valve stem and concealing the Wall opening and supplemental' valve stem. 4

2. The combination With a valve casing having a chamber adapted to it into a wall openin of a main valve and stem for operating t e same, a supplemental cut olf valve and stem for operating the same, and an escutcheonvarranged upon the main valve stem and concealing the valve casing chamber and supplemental valve stem.

3. The combination with a valve casing, valve and stem, said stem being. adapted to extend through a Wall opening, of' a supplemental cut olf Valve and its stem, a housing for said stem connected to the valve casing and adapted to extend into the wall opening and means connected to the main valve stem for covering the Wall opening.

4. The combination with a valve casing, main valve and stem, said casing having a chamber in which the main stem islocated, said chamber being adapted to extend into a Wall opening,I the main valve stem extending beyond saidvwall, of a housing connected to the valve casing and parallel with the chamber, said housing being also located in the Wall opening, a'valve and stem in said housing, said valve being a supplemental cut off valve and adapted to close the inlet opening in the valve casing, the outer end of said supplemental valve stem being adjacent the outer edge of the Wall opening.

'5. The combination with a valve casing having two openings in its partition, of a main and supplemental valve, a mainand 6.The combination with a valve casing I having tWo openings, one of said openings having a tubular seat arranged therein, of a main valve seating upon said seat, a stem chamber for said main valve and stem, a supplemental valve and stem, said supplemental valve being adapted to close the inlet opening in said lvalve casing, a housing connected to the casing and in which the supplemental valve stem works, said housing for said valve, said valve casmg having av and basing chamber being adapted for location in a Wall opening, the outer end of the supplemental stem being located adjacent `the outer edge of said opening, means for closing the ends ofthe chamber and housing, the cuter end of the supplemental stem'being shaped to receive an operating tool, an operating handle upon the end of the'main stem and means carried on said stem for covering the wall opening and concealing theouter en s of said chamber and housing n testimony whereof,I hereunto aiix my I i signature. l L g V- LEON BLOCH.
